The MAMA detectors cannot be used for pure parallel observing. For Cycle 23, coordinated parallels will not be allowed with STIS MAMA imaging modes and the STIS NUV-MAMAPRISM mode. However, coordinated parallels will be allowed with other STIS MAMA spectroscopic modes, provided that an explicit ORIENT is specified and precise RA and Dec coordinates for the parallel field are given. The MAMA detectors are subject to bright object protection limits; see Section 2.8.
